USB - Universal Serial Bus connectors are intermediateries for connections between Computers and Hardwares.These USB connectors let you attach everything from mice to printers to your computer quickly and easily. Printers connected to parallel printer ports, and most computers only came with one. Things like Zip drives, which need a high speed connection into the computer, would use the parallel port as well, often with limited success and not much speed.The operating system supports USB as well, so the installation of the device drivers is quick and easy, tool. Anyone who has been around computers for more than two or three years knows the problem that the Universal Serial Bus is trying to solve in the past, connecting devices to computers has been a real headache.
The Universal Serial Bus gives you a single, standardized, easy to use way to connect up to 127 devices to a computer. Modems used the serial port, but so did some printers and a variety of odd things like Palm Pilots and digital cameras. Most computers have at most two serial ports, and they are very slow in most cases.Devices that needed faster connections came with their own cards, which had to fit in a card slot inside the computer case.
